For me, this is why it's such a big deal: I don't think it has to be porn to be used against you. It just needs to be some minor character flaw that breaks with your public image.

And I guess more troubling still, this kind of stuff could be used to blackmail normal people in the same way revenge porn is. What about threatening to reveal your porn habits to friends & family?

Again, doesn't need to be porn. What about your browsing history for medicine, self-help etc? All that stuff could be used to blackmail someone, especially if they're psychologically vulnerable.
